TORQUE SENSING BRAKING CONTROLLER

A torque sensing braking controller senses directly the braking torque exerted by a rotating element (14, 114, 214, 314) upon at least one friction element (20,222,320 and 332) of the brake (10, 210, 310), such that the sudden decrease in torque which occurs when wheel lock-up and skidding occurs is...

Beschreibung
Zusammenfassung:	A torque sensing braking controller senses directly the braking torque exerted by a rotating element (14, 114, 214, 314) upon at least one friction element (20,222,320 and 332) of the brake (10, 210, 310), such that the sudden decrease in torque which occurs when wheel lock-up and skidding occurs is sensed and results in the communication of an increased output pressure to oppose outward displacement of at least one differential area piston (40 and 50, 240 and 250, 340) by fluid pressure received from the master cylinder, the increased output pressure causing the piston to reduce braking force exerted by the friction element against the rotating element (14, 114, 214, 314) so that the rotating element may recommence rotation. The torque sensing braking controller may be utilized in drum brake (10), duo-servo drum brake (210), and disc brake (310) assemblies. In each instance, the brake utilizes the sudden drop in braking torque to create an increased output pressure which opposes displacement of a differential area piston and effect release of the rotatable element so that wheel rotation recommences.
